3d spinning car help

Hi guys, I am trying to create a similar effect of that found on flashloaded components(control VR)
What i have at the moment is a sequence of images and a mouse event that checks the position of the mouse when pressed. This then sets a function to move the car in either direction.

I have 2 problems/questions(how to)

  1. using easing to slow the spin to stop.
  2. how to drag and spin.

Any help would be very much appreciated.

thanks
Paul
